ASSEMBLY
1.
Specimen holder:
a.
Rotate coarse focusing knob to move stage platform to its lowest position.
b.
Remove two knurled screws from mechanical stage platform.
c.
Place specimen holder on stage and using the two knurled locking screws, attach specimen holder to mechanical
stage.
2.
Rubber eye shields
a.
Eye shield is designed with two diameters, the largest is for mounting over the eyepiece.
b.
Slip rubber eye shield over top edge of eyepieces, with smallest diameter facing user.
c.
These shields help block out undesired light reflections, and to position your eyes at the proper point above the
eyepieces.
OPERATION
1.
Place microscope directly in front of you in a manner, which permits you to comfortably look into the eyepieces. Note that
the head of microscope rotates 360º, permitting you to operate the microscope from the front or from the back, whichever
is most convenient for you. It also permits convenient sharing of microscope by more than one user, by simply rotating
head, without needing to move entire microscope.
2.
Assure that light is available for illuminating the specimen.
a.
Your microscope has special LED illumination that is powered by 3 rechargeable AA nickel metal hydride batteries
(supplied). These batteries may be recharged, as required, using the recharger (supplied). Each set of batteries may
be recharged approximately 500 times before replacing, and each charge will provide up to 50 hours of microscope
operation. The LED component (bulb) will last for up to 50,000 hours before replacement is required.
WARNING
DO NOT USE regular AA alkaline batteries. Use of other than rechargeable AA nickel metal hydride batteries
could result in batteries exploding during recharge. ONLY USE THE SUPPLIED SWITCHING BATTERY
RECHARGER WITH AUTOMATIC "TRICKLE CHARGE".
b.
It is recommended that you charge the batteries before initial use and after prolonged storage as the batteries may
have discharged. Plug output cord from battery charger into DC recharging socket located on back of microscope
base. Your automatic switching recharger operates on 100 to 240 volts AC 50/60 Hz. Plug charger into your AC wall
outlet. Battery recharger is equipped with an automatic "trickle charge" feature, the red LED indicator lamp located on
recharger will be illuminated when batteries are receiving maximum charge. After batteries are charged, the red LED
indicator lamp will turn to green and charger automatically switches to "trickle charge". The charger can be left
plugged in, but for safety reasons it is a good idea to disconnect the charger from the AC wall outlet and the output
cord from recharging socket after 12 hours. Batteries and charger may feel warm when charging, and unplugging the
recharger is a safety precaution.
Note that your microscope can be used during recharging. Simply turn "on/off" switch on back of microscope base to
"on" position and proceed as follows. In case of equipment malfunction, see "Troubleshooting" procedure.
2.
Interpupillary adjustment of binocular viewing head.
a.
Look through microscope and adjust distance between the two eyepiece tubes by grasping the sliding mounts to left
and right of eyepieces and sliding together or apart.
b.
When a full field of view is observed through both tubes, and images blend into one, interpupillary distance is
corrected for your eyes. Check the interpupillary scale and note index reading for future reference, in case other users
will be changing this adjustment from time to time.
c.
Adjust the diopter scales, located on each eyepiece tube, to the same numerical value as indicated on the
interpupillary scale. This must be done in order to maintain parfocality of objective lenses. If interpupillary distance is
changed, adjust eyepiece diopters accordingly.
3.
Focusing the microscope.
a.
Position the 4x objective lens into the optical path, making sure that lens is properly indexed in its click-stop position.
b.
Swing moveable finger on specimen slide holder outward. Place specimen slide (cover slip up) on top of stage
surface against fixed side of slide holder. Slowly release moveable finger until it makes contact with specimen slide.
